OILING DEVICE.

Application filed July 12, 1910. Serial No. 571,644.

Specification of Letters Patent.

Patented June 20, 191-1.

To all whom it may concern:

Be it known that 1, DAVID F. HERVEY, citizen of the United States,residing at Logansport, in the county 'of Cass and State of Indiana,have invented certain new and useful Improvements in Oiling Devices, ot'which the following is a specification.

My invention relates to improvements in hard oil or hard grease plugoiling devices in which plugs are used to force the hard greasedownwardly on to the crank pin.

1 The object of my invention is to provide a locking device for oil cupsin which plugs are used to force the hard grease downwardly into theaperture of the driving rod.

Another object of the invention is to provide a locking device and hardgrease plug, which, by its construction, will not only look the plug andprevent its turning and thereby losing out, but will provide means forthe passage ofair through the same, there-by cooling the plug somewhat,and preventing undue expansion as would be the case if p the driving rodshouldbecome heated.

Other objects and advantages of the invention will hereinafter appearand the novel features thereof will be particularly pointed out in theappended claims.

The invent-ion is clearly illustrated in the accompanying drawings,which, with the numerals of reference marked thereon, form a part ofthis specification, and in which Figure 1 is a longitudinal sectionthrough my improved device shown applied. Fig. 2

is a detail longitudinal section of the plug. Fig. 3 is a section atright angles to Fig. 1

showing the plug in elevation. Fig. 1 is a.

detail plan showing the relative location of the slot and notches. Fig.5 shows in positions at right angles to each otherthe stem. Fig. 6 is aplan of the device complete.

Like letters of reference indicate like parts throughout the severalviews.

Referring to the several views, the principal parts are as follows: plug8, spring 24, stem 11, knob 17 and plug 9. Plug 8 is hollow for most ofits length and also slotted for part of its length. The periphery of theplug 8. is threaded. The plug also contains a small hole, recess, ornotch 16. The upper end of plug 8 is finished like a nut 18 so a wrenchmay be used when necessary.

The bore of the plug 8 contains a spring 2 1.

,and a T shaped stem 11. The stem is provided with a rod 13 at rightangles to the. lower end. The rod 13 is secured in the stem 11 byscrewing therein. The stem 11 is also provided with a knob 17 in orderto give a firmer grip on the stem 'by the fingers when it is desired toraise the stem. The knob 17 is secured to the stem 11 by a rivet 23. It

can also be secured to the stem 11 by thread ing the stem and screwingthe knob on.

At any time it is desired to use the plug 8 and force the hard greasedownwardly into the aperture 21, take hold of the stem 11 at knob 17 andraise the stem until the rod 13 in the stem 11 is opposite the notch 16.Then give the stem 11 a slight turn with the hand until the rod 13-drops into the notch 16. The lifting of the rod 13 from the slot 14unlocks the plug 8 and it can then be screwed down or taken outentirely. To

look the plug again, remove the rod 13 from hole 16 and let it rest inslot 14, which is a groove in the side rod 10. The rod 13 will be forcedto remain therein on a'ccount'of the spring 24 exerting a downwardtension.

To remove the stem 11 from the plug 8 remove the plug 9 therefrom byremoving the rivet 19 and unscrewing. The knob 17 of stem 11 should alsobe removed. The plug 9isalso designed to answer the purpose of a socketnut. Q

What I claim as new and desire Letters Patent for is:

1. The combination with a side rod havinga threaded bore, of a cylinderhaving threaded engagement therewith and having ,within the cylinder,lateral means onthe stem movable through the slot of the cylinder forengaging said notch, said lateral means engageable also in recesses inthe outer end of the driving rod.

2. A hollow plug longitudinally slotted and provided with a. lateralrecess opening into the slot, means within which said plug is endwisemovable to serve as a plunger, a

stem in the plug, lateral means on the stem for engagement with saidrecess by partial rotation of thestem, a plug at the inner end of saidhollow plug and removable means engaging the same.

3. A hollow plug longitudinally slotted and provided with a lateralrecess opening into the slot, a stem in the plug, lateral means on thestem for engagement with said recess by partial rotation of the stem, aplug at the inner end of said hollow plug, removable means engagingthesame, a spring in,

the hollow plug exerting an inward tension on the stem, and a side rodhaving a slot in the end receiving said lateral means, and having athreaded bore in which said hollow plug is endwise movable to form aplunger.

4. A hollowplug longitudinally slotted and provided with a lateralrecess opening into said slot, a stem in the plug, means on 'the stemfor engagement with said recess by a partial turn of the stem, a springinthe 10 plug, said means extending through the slot and the plug havingscrew threaded engagement with a fixed support and serving as a plungerfor forcing out the grease.
